Orion Moto has built a reputation for offering affordable and reliable dirt bikes, serving both newcomers and seasoned riders. However, with the recent removal of the EPA exemption for off-road and competition-use-only dirt bikes, Orion Moto faced a significant challenge. The company had two options: either install costly catalytic converters and a Secondary Air Injection System (SAS), which could reduce performance, or shut down operations entirely. But Marc Croft, one of Orion Moto’s owners, was determined to find a better solution.

The SmartCarb Solution

Marc began exploring alternatives that would meet the new environmental standards without compromising performance. That’s when he discovered SmartCarb and their SC3 carburetor. The SC3 offers impressive benefits, including up to a 10% increase in horsepower, a 30% improvement in fuel efficiency, and a 50% reduction in emissions. These advantages seemed like exactly what Orion Moto needed to keep its bikes performing well while trying to comply with the new regulations.

Collaboration with SmartCarb

After learning about SmartCarb, Marc and the Orion Moto team reached out to discuss the potential of the SC3. After extensive testing both on the dyno and in the field it was clear that the SC3 equipped bikes had what it takes! The first model to feature the SmartCarb SC3 stock will be the Orion RXB250, one of their most popular bikes. This marks an exciting step as Orion Moto works towards meeting EPA certification standards.

Looking Ahead: EPA Certification and the Future

Although EPA testing has not yet started, Orion Moto is focused on moving forward with the SC3 and achieving certification. The ultimate goal is to obtain EPA certification, including in California, so Orion Moto can offer its bikes in all 50 states. While the journey is ongoing, the company is optimistic that the SC3 will play a crucial role in reaching that milestone.

By partnering with SmartCarb, Orion Moto is ensuring that it can continue delivering high-performance dirt bikes while staying aligned with environmental standards. This collaboration represents a significant step forward, combining innovation and responsibility in the dirt bike industry.


Orion Moto’s decision to offer the SmartCarb SC3 as stock on the RXB250 demonstrates their commitment to both performance and environmental responsibility. While the journey toward EPA certification is still in progress, Orion Moto is on the right track to offer cutting-edge, high-performance dirt bikes that meet the needs of modern riders.
